svn commit: r249565 - head/sys/dev/ath

[Adrian Chadd]

Author: adrian
Date: Tue Apr 16 20:21:02 2013
New Revision: 249565
URL: http://svnweb.freebsd.org/changeset/base/249565

Log:
  Use a per-RX-queue deferred list, rather than a single deferred list for
  both queues.
  
  Since ath_rx_pkt() does multi-mbuf frame recombining based on the RX queue,
  this needs to occur.
  
  Tested:
  
  * AR9380 (XB112), hostap mode
